Etymology

Origin of tough

First recorded before 900; Middle English (adjective); Old English tōh; compare Dutch taai, German zäh(e)

Explanation

The adjective tough is good for describing hard times. If you just got mugged, lost your job, got the flu, and broke your toe, you're having a really tough week. Tough means "strong, hard, unbending," and you can use it to describe many different things, like a tough exam, or a tough piece of beef jerky, or a tough day that you just want to be over. If a judge punishes criminals harshly to set examples, she's "tough on crime." We call people toughs if they seem likely to beat you up. Tough things are made to withstand a beating, like the tires on your mountain bike. Pronounce: TUFF.
